Yondoo provided router, has "password" as admin pw, won't let us change it

What's the problem with double NAT?  I can't imagine an elderly mom trying
to host Xbox games - which is 95% of the problem with double NAT these days
(the other 5% being Ubiquiti bros having to access their Unifi router from
anywhere).

Your screenshots didn't come through, I suspect it's stripped via the
mailing list, but there's no model number specified anywhere.

NANOG really isn't the best place for this, but I don't know where else you
would be able to go besides what you've already done:  Yondoo support.
